.Application'led February 7, 19.18. .Sera1/No.215,833.

Portland, inthe county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Awls, of which the following vis a specification.y

My invention relates to a shoemakersawl.

I particularly aim to provide a device whereby holes through which thread designed to secure a sole to a shoe may be rapidly and expeditiously provided. At. the present time, markers are vused to indicate the location of the desired holes. However, after the indications are described, eachhole has to be separately punched. The present invention dispenses with this incidental loss of time and labor. I have found that merely a wheel provided with a number of projections will not work satisfactorily. It is essential to provide lugs intermediate the points to limit the depth of penetration of the points into the leather so that turning of the Wheel will be free and easy. Further I aim to provide a means whereby the distance of holes from the marginal edgev of the sole, may be determined and varied at will.

Additional objects will become apparent as the device is described hereinafter with respect to accompanying drawings, illustrating one preferred embodiment, and wherein Figure 1 is a side elevation of the improved awl;

Fig. 2 is a cross sectional View Von the line 2-2 of Fig. 1;

Fig. 3 is a plan View of the article, with the handle removed;

Fig. 1 is an enlarged front elevation of the awl member; and,

Fig. 5 is a side elevation or edge view of the awl member.

Referring specifically to the drawings, I provide a supporting member 6 of any suitable shape and which is adapted to project from a handle 7. The handle 7 may be of any form desired and any means which is obvious may be employed to secure it to the member 6. I have shown by way of eX- ample, a shank 8 integral with the handle and machined to a piercing point at 9. The member 6 may therefore be driven into the handle which as usual is of wood. The member 6 is provided with a transverse aperture at 10 through which the shaft 11 Y bears.

rides and which isV secured rigidly inplace in said aperture by meansof a'set screw 12. The set screw bears .directly against the shaft` as will be obvious.

The Vmarker member comprises a disk or wheel having a central opening 14 bymeans of which it is mounted on a reducedxportion l5 of the shaft 11. Portion15 therefore is a bearing and a shoulder is provided yat its junction .with the remainder of the shaft against which shoulder the wheel or disk 13 Asst screw 16 lis fastened in'one .end of theshaft 1l and overlaps the freezend of the bearing portion 15 and the disk 13, so as to secure it ,in place. Disk'13 however is freely rotatable on the bearing 15.

Referring to the specific construction of the disk 13, the disk is made in one piece Iand has a plurality of equidistant peripherally arranged awl points 17. These points as shown, are substantially pyramidal, but they may be conical or of any shape desired or preferred. Intermediate the points 17', lugs 1S radiate from the disk. These lugs preferably have a curved or otherwise blunt outer face at 19 and they are of less length than points 17. According to the length of the lugs 19, the depth of penetration of points 17 into the leather is gaged or limited.

In this way, the piercing points do not eX- tend into the leather in such a way that the wheel will not freely turn. The points 17 therefore simply pierce the leather as far and to as great an extent as the lugs 19 will permit. These lugs directly engage the leather and in addition to limiting the movement of the points 17, by reason of their rounded outer edges serve to assist the turning of the wheel.

As the device is operated, the distance of the row of holes from the marginal edge of the sole is first determined and shaft 11 and disk 13 adjusted accordingly upon properly loosening and tightening the set screw 12. The article is then manually moved so that the points 17 will provide the holes in the leather.

Particular attention is called to the fact that the member 6 is provided in any preferred shape but particularly is enlarged at 20 into a gage plate adapted to extend beneath the teeth 17 and to engage the margi nal edge of the sole being pierced.

Since merely the preferred embodiment has been illustrated and described, it is to be understood that changes in the details may be resorted to within the spirit and scope of the invention as defined by appended claims.

I claim 1. A tool of the class described having a supporting gage to coperate with the sole of a shoe, a shaft slidable transversely thereof, a set screw carried by the gage to secure the shaft in rigid relation therewith, an awl member carried by the shaft, and means to rotatably support said member on the shaft.

2. A tool of the class described having a supporting member, said member bein reduced to provide a bearing and a shou der, a rotatable awl member mounted on the bearing and against said shoulder, and means' overlapping the bearing and said awl member to secure the awl member on the bearing.

3. A tool of the class described having a rotatable awl member provided with a plurality of awl points, and a means disposed intermediate said points to limit their extent of penetration into the article to facilitate turning of the awl member.

4. A tool of the class described havin a rotatable awl member provided with a p urality of awl points, and means disposed intermediate said points to limit their extent of penetration, said means having a curved surface to engage the article to further assist in ready .turning thereof.

5. A tool of the class described having an .awl memberprovided with a plurality of awl points, and lugs to limit the'eXtent of movement of said points into the article,

said lugs being disposed intermediate the points and terminating short of the piercing points thereof, l

In testimony whereof I afliX my signature in presence of two witnesses.

JOHN R. SWENSON.
